This paper analyzed the reasons for the stubbornly low labor productivity in East Germany. Specifically, we distinguished between two main causes, namely worker characteristics (e.g. skills) vs. job characteristics (e.g. capital or infrastructure). We built a spatial labor market model that allows for commuting. If less favorable worker characteristics cause the low labor productivity in the East, then there will be no commuting, and the unemployment rate increases discontinuously at the former border.
From a general survey of the later Roman empire from ca. 250 to 700, the course "History 11111: The fall of Roman Empire" is shifting to an investigation of the question of the fall of the Roman Empire.
It will emphasize archaeology, primary written sources in translation, web-based resources, and the application of new natural scientific methods to historical and archaeological problems across the entire Roman world.
A dataset provided by the New York City Housing Authority consisting of ~20,000 condominium addresses with sale dates and dollar amounts was geocoded. Dot density maps were made displaying the locations, sale amounts, and year sold for the properties (First map below).
German electoral boundaries from a 19th Century map were converted to vectors, built into polygons, and attributed. These were used to visualize 19th Century German census voting patterns. Service provided for Daniel Ziblatt, FAS – Political Science.
Chinese population data go back 2000 years. The challenge was to distribute this population across the landscape in a manner that most likely reflects patterns of settlement, rather than assuming that population density within an administrative unit is uniformly distributed.
